2. Example on Design Shallow foundation
A rectangular shallow foundation is to be placed at depth of 2 m below
the ground surface of c, Φ soil and water table is at 1 m below the
ground surface.
Find the dimensions of the foundation for the column load is kN.
Assume L = 1.5 B and factor of safety = 4

9. Example on two- way moments
A square footing is 1.8 X 1.8 m with a 0.4 X 0.4 m square column.
It is loaded with an axial load of 1800 kN and Mx = 450 kN • m;
My = 360 kN • m. The soil has Φ = 36° and c = 20 kPa. The
footing depth D = 1.8 m; the soil unit weight y = kN/m³;
the water table is at a depth of 6.1 m from the ground surface.
